 Do not get this product wet to prevent heat generation/ignition/product failure. When this product gets wet,stop using it.
 Do not connect metal excepting wiring to terminal in order to prevent heat generation/ignition.
 Do not get this product near the inflammables/combustible chemicals/gas to prevent fire.

 Connect specified power supply.
Connecting power supply beyond specification causes fire/product failure.
 When dust is on the terminal, wipe it off after power is OFF to prevent fire.
 Follow the below-mentioned procedure when abnormality (fuming/bad odor) happens.
(1) Stop using after power and input are OFF.
(2) Have a contact with us or sales agent.

 Do not use this product in a environment of high temperature/high humidity to prevent any damage.
 Do not touch the terminal during operation to prevent electric shock.
 Do not pull/bend connecting cable with force. Cable damage causes heat generation/burn and contact failure
leads to equipment damage.

Places where corrosive gas (SO2 / H2S / etc.)(１) is generated.
Places where dust is generated.
Places with much vibration and shock.
Places with influence of external magnetic field (２).
Note (１) Corrosive gas = Sulfur dioxide SO2 / Hydrogen sulfide H2S / etc.
Note (２) Large current bus / saturable reactor / etc.
Wipe off dirt on the surface with dry cloth softly. Keep in mind that strong rubbing of nameplate leads tocharacter disappearance. Organic solvent is not appropriate for cleaning.
Mercury component, Nickel-cadmium battery are not used in this product.
This product is disposed as an industrial waste (Non-inflammable).
This product is not dust-proof structure and not waterproof structure. In using by the outdoor panel, pleaseavoid the place, which dust causes. And, please install in the place that requires neither rain nor waterdrop.

1. Explanation of product1.1 Product outline
This product is the alarm setter of the plug-in structure which considers a DC voltage (or DC current) signal
as an input, and outputs the relay contact signal of four points (maximum) as compared with the set-up operation
set value.
This product is the type corresponding to the software that has a LCD function and a scale can set up arbitrarily
according to the amount of processes. The real scale display function of an input, the dead band setting function,
the contact delay setting function, and the starting delay setting function are built-in. It can correspondto various process instrumentation flexibly.

1.2

Features of product Setting accuracy is ±0.1％ (％ for input span). Display accuracy is ±0.1％±1digit (％ for input span).
 Between input, output, auxiliary supply and cases, withstand voltage is AC2000V design.
 The display of real scale by LCD. And, setting can carry out freely by the front button switch.
It can correspond to scaling change etc.
 Nonvolatile RAM offers the power failure guarantee of the set value.
 Sufficient derating of uses parts, and reduction of inside generation of heat improves reliability.
 The back light is turned on at the case of key operation. 30 seconds after key operation is completed, theback light puts out the light.
 By the pre-alarm function, the efflux in contact delay time is displayed by blinking of a monitor lamp.
(ON/OFF of prealarm can be selected by setting.)

A monitor lamp is blinked among contact delay time until excitation of a relay after operation value detection.
Blinking of a monitor lamp will be gradually fast, and when the point of contact delay time passes, a monitor
lamp is lights up.

In DC load switching, transition of a contact may start and a contact may
not return by uneven connection.
A contact evaporates locally with arc heat, what carried out contact
evaporation to + polarity → - polarity carries out the adhesion depositionof this, and a single-sided convex opposite side serves as a concave.

Please be careful of wiring enough. And, check in the place which has combustibles, an inflammable medicine,
inflammable gas, etc. in environment is also dangerous.
 When inductive loads (electromagnetic relay, etc.) are connected to output contact, It recommends attaching
diode (or surge killer) etc. near the load.

Cautions on mounting
 State of mounting
There is no limit of mounting position. Mounting instruction can select 35mm width DIN rail mounting andscrew mounting. In screw mounting, please mount with M4 screw. (However, the screw is not attached.
And, please give the mounting torque of a screw as 1.08 to 1.47N･m (11 to 15kg･cm)).
Should establish of side-by-side mutual mount space 5mm over up. A vertical interval should prepare
space 90mm or more in consideration of radiation and a wiring space.
 State of wiring
Please separate wiring of input and output and perform consideration to noise. And, please separate froma line with the power line used as the source of a noise and steep voltage, and current as much as possible.
Please use shielding wire for the bottom of the remarkable environment of a noise.
 Conditions of environment(1) The range of the temperature and humidity of environment.
Please give temperature and humidity as a next range from operation of each device.
Temperature：-10 to +55℃，Humidity：5 to 90％RH (Non condensing)(2) Environment atmosphere
The case has sealing construction. However, be careful of employment under environment with much dust.
Please consult on the occasion of the employment under corrosive gas environment, such as hydrogen sulfide
gas (H2S) and chlorine gas (Cl).

Relay output circuit

5.2 Principle of operation(1) The inputted voltage or current passes along a filter protection circuit, and becomes the DC voltage below
constant voltage. This voltage goes into an amplifier.
(2) The input is converted into the suitable voltage range in an amplifier.
of an A/D converter.

This voltage constitutes an input(3) The data converted into digital one by the A/D converter are sent to CPU. A/D converter has 16-bit resolution
and performs operation and conversion with 1MHz clock. Based on the scaling range that had this data set
up, it calculates within CPU. And the measurement value scaling by the LCD is displayed.
(4) The operation value and measurement value, which was set up beforehand, are compared, and the relay and LED
are operated.
(5) The front pushbutton switch makes each setting change.
(6) The value set up by the switch is saved at non-volatile memory (E2PROM). ROM has the capacity of 128×16 bits.

6. Inspection
6.1 Receiving inspection
In case you inspect at the time of receiving, please perform after reference the following.
(1) Structure
Inspection of an outline dimension, mounting dimension, and appearance.：Please perform with reference todimensional outline drawing.
(2) Performance
Please do a reserve energization (warm-up) for 15 minutes after a power supply apply. After that, please
conduct performance inspection. Performance inspection is performed with reference to 7.2 "calibration
method".

6.2 Periodic inspection
Please perform the following item if needed.
(1) Please check each set value.
(2) The accuracy test of indicated value.
An input tests indicated value as two to five points.
(3) Alarm output operation and setting accuracy.
The check with normal ON/OFF operation. The accuracy of operation value and reset value (dead band) is tested.

7. Check, calibration and maintenance
7.1 Check
It is not necessary to check especially every day. Please be periodically careful of the next item.
(1) It is checked whether a body and socket combination are normal (is a lock a totality?).
(2) It checks for the slack of wiring, and the slack of a captive screw.
(3) It will remove, if dust has adhered to the case.

7.2 Calibration
Calibration is performed in the calibration circuit of the rightfigure.
(1) Please do a reserve energization (warm-up) for 15 minutes after
a power supply apply.
(2) When the input equivalent to the minimum display is applied,in order that it may become the minimum display, set value
CBIAS is set up.
Next, when the input equivalent to the maximum display is applied,in order that it may become the maximum display, it sets up
by set value CSPAN.
Calibration is finishing, if the above is checked again andthe display is correct. In addition, please refer to the
4.5 section "set value change mode" about setting of set
value CBIAS and CSPAN.

7.4 Countermeasures against troubles
As our principle, we recall product in question and repair it. If judged as product failure, have a contact withus or sales agent for repairing work (Also have a contact with us or sales agent for specification change).
Product failure which we are not responsible for (When responsibility in manufacturing process is not recognized,
when product is disassembled/remodeled, in case of false operation by customer, etc.) is beyond our warranty.
